Why not just use AC to heat the tubes?
Maybe I'm just paranoid but I wouldn't want .63 volts of sawtooth anywhere near my audio circuits.
In all but the output stage chassis my power supplies are outboard.
All power supplies are critical inductance choke input.
I like things to be "calm" but that may just be me. :-)
